Scientists have discovered that much of Greenland's ice sheet is melting
at an unusually rapid pace:

Scientists said the "unprecedented" melting took place
over a larger area than has been detected in three decades of satellite
observation. [...] The thawed ice area jumped from 40% of the ice sheet
to 97% in just four days from 8 July.

Although about half of Greenland's ice sheet normally sees surface
melting over the summer months, the speed and scale of this year's thaw
surprised scientists, who described the phenomenon as "extraordinary".

Scientists also reported that much of the ice is re-freezing, so they remain puzzled as to the reason for the unusual thaw. Link

Oh, Alex, unfortunate lad: Wrong, wrong, wrong and, dare I say it, WRONG. If you find the original item and read to the end you will read:

""Ice cores from [Summit Station in central Greenland] show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time," says Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data."
